Expert Solidity Development

We need the intended behavior of the contracts in plain language, the target networks, and any protocols or tokens the code must interact with. If contracts already exist, repository access lets us assess them directly. We convert this into a written specification before development begins, so the audit later has something to verify against.

You do. All Solidity source, test suites, and deployment scripts land in your repositories, and control of deployed contracts is transferred to your addresses. Any developer who knows Solidity can pick up where we left off; that is deliberate.

We agree the measure before writing code: audit findings resolved, tests covering the specified behavior, and gas costs within an agreed budget, plus a business baseline where the contracts replace an existing process. That baseline is recorded first and the same number is tracked after go-live. Vague success criteria produce vague contracts, so we refuse to start without them.

After deployment we monitor contract activity, operate admin and upgrade functions under agreed controls, and respond to incidents, typically on a retainer. Because Solidity contracts cannot be silently patched, the support plan is designed before launch, including what happens if a vulnerability is found in production. Documentation and runbooks transfer to your team as standard.

We prepare a scoped proposal after an engineering call, based on contract complexity, integration surface, and audit requirements. Engagements run fixed-scope for defined builds or as a retainer for ongoing protocol work. We do not publish per-contract prices because two contracts of the same length can differ widely in risk.
